Introduction

Modern ASKO refrigerators are designed to operate quietly, but occasional noises may occur during normal operation. While some sounds are expected, unusual or loud noises may indicate an issue requiring attention.

Understanding the type of noise can help identify whether the sound is normal or needs troubleshooting.

Common Refrigerator Noises and Their Causes

1. Humming or Buzzing Sound

A low humming sound usually comes from the compressor. This is normal when the refrigerator is actively cooling.

If the sound becomes louder than usual, check:

• refrigerator is level
• appliance is not touching the wall
• floor is stable

2. Clicking Sound

Clicking noises often occur when the compressor starts or stops.

Occasional clicking is normal, but frequent clicking may indicate:

• faulty start relay
• compressor issue
• electrical problem

3. Rattling Noise

Rattling sounds may be caused by loose components or items placed on top of the refrigerator.

Check:

• items on refrigerator top
• loose screws
• water line position

Ensure the appliance is properly installed.

4. Fan Noise

ASKO refrigerators use internal fans for air circulation. If airflow is blocked, the fan may produce unusual noise.

Inspect:

• freezer compartment for ice buildup
• food items touching fan cover
• vents for obstruction

5. Gurgling Sound

Gurgling or bubbling noise is caused by refrigerant flowing through cooling lines. This sound is normal.

How to Reduce Noise

To minimize refrigerator noise:

• keep refrigerator level
• ensure proper ventilation space
• avoid placing heavy objects on appliance
• clean condenser coils
• keep refrigerator away from heat sources

When Noise Indicates a Problem

Seek professional repair if noise is:

• very loud
• continuous
• increasing over time
• accompanied by cooling issues

Timely maintenance helps avoid major repairs.
